LAM P-SHADE.

Application filed August 9, 1898.

To all whom it may concern.-

- Be it known that I, REINHARD W. PITTMAN, a citizenof the United States, residing in New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Lamp-Shades, of which the following is a specification.

This invention relates to lamp shades or reflectors, and more particularly to that class of shades especially adapted for use in connection with incandescent lamps.

One object of the invention is to provide a shade having improved means for securing the same in position, and more particularly an improved shade which can be secured in position directly onto the glass bulb or globe of an incandescent lamp, whereby the socket portion thereof will be left free to be attached to a lamp-bracket.

A further object of the invention is to provide a shade in which the means for maintaining the same in position on a lamp is rigidly secured to one part of said shade and detachably secured to another part thereof and is automatically adjustable to permit the use of the shade with various sizes of lamps.

In the drawings accompanying and forming part of this specification, Figure 1 is a View of one form of this improved shade in position on an incandescent lamp. Fig. 2 is a view similar to Fig. 1, with the shade adjusted into a different position. Fig. 3 is a sectional plan view thereof, the section being taken in line a a, Fig. 2, the dotted lines showing the detachable end of the spring connection disconnected from the shade. Fig. 4c is a detail view showing one means of securing one part of the spring connection to the shade. Fig. 5 is a view showing the spring secured to the shade in a somewhat different manner. Fig. 6 is a View of an incandescent lamp adjusted in an upward direction, with this improved shade in position to properly reflect the light. Fig. 7 is a view of the blank from which this improved shade is formed.

Similar characters of reference designate corresponding parts in the different figures of the drawings.

In practice itis frequently desirable to sup Serial No. 688,172. (No model.)

point it follows that when the lamps are supported by brackets of this character it is impracticable to use a shade, and vice versa.

To avoid the disadvantages above pointed out, I have provided an improved shade which can be readily secured in position directly onto the glass lamp bulb or globe, thereby leaving the lamp holder or socket 0 free for attachment to a lamp-bracket, and which shades can be adjusted into various positions in a circular path to reflect the light in any desired circular direction and will always be in position when the lamp is swung upwardly relatively to its supporting means (see Fig. 6) to properly reflect the light.

In one form thereof herein shown and described the shade or reflector (designated in a general way by A) is preferably formed as substantially semicircular or semiglobular, whereby it will be of such shape that it will substantially encircle one-half of an incandescent-lamp globe or bulb, (designated by B,) and for this purpose I provide a blank (designated generally by E) preferably formed in one piece of any suitable material and may be of sheet metal, and which blank is shown as bulb-shaped, having a bulb portion 0 and a neck portion 01 of less diameter than said bulb portion 0. This neck portion in some constructions may terminate in ear portions 6, projecting outwardly from said neck portion, and which blank, if desired, may be cut away at the top thereof intermediate said cars. This blank is shaped to form a neck 2 of the shade A, adapted to partially encircle and frictionally engage the neck 3 of the glass bulb B and a shield or reflecting portion 2', which flares outwardly from said neck 2, (see Fig. 2,) whereby there is provided a substantially semicircular comically-shaped shield or reflector, the apex of which is adjacent to that portion of the lamp-bulb having substantially the largest diameter.

One means for securing this improved shade in position relatively to the glass globe or bulb comprises a device which will permit the ready removal of such shade when desired, while at the same time it also permits rotary adjustment of the shade relatively to the lamp, and which device is shown as a laterally-adjustable member, shown in one form thereof as a spring, such as a coiled spring 8, one end of which is rigidly secured to one side of the shade in any suitable manner-as, for instance, by being soldered thereto or by having a plurality of its coils passed through a series of apertures in the shade-while the opposite end of said spring is detaohably or removably secured to the other side of said shade in any suitable way. In one construction thereof the ear portions e may be bent or flared outwardly, forming ears 4: and 5, to one of which, as the ear 5, one end 7 of the coiled spring is rigidly secured in a similar manner to that shown in Fig. 4, or only one of said ear port-ions e may be flared outwardly, forming the ear 4, the opposite unbent ear 5 having a series of apertures through which a plurality of the coils pass. In either case the opposite part of the spring 8 is removably secured to the other car 4:, preferably by engaging said ear between two adjacent coils, whereby the shade will be held in position by its frictional engagement with the lamp, thereby doing away with threaded or similar clamping means. By this mode of fastening it will be readily seen that the shade may be secured in position adjacent to any size of bulb-neck, since the fastening means is longitudinally adjustable in a circular direction, owing to the spreading of the coils, and can thereby be adjusted so that the ear 4 can be received between any two adjacent coils either at the end of the spring or remotely therefrom, as desired. For the purpose of manipulating this spring in the manner above set forth it is shown provided with a fingerpiece 10, which may comprise one of the coils disposed in position transversely of the other coils. By flaring or bending the ears backward the coils of the spring 8 are prevented at its detachable end from slipping off the shade, as would be their tendency if the ears were not so shaped.

To maintain the shade away from the lampbulb at that part thereof which becomes the most highly heated, and thereby permit the circulation of air between the bulb and the shade and also prevent injurious effects to the inner side of the shade, especially when it is enameled, suitable means is provided which in the construction shown comprises an adjustable device, shown in the present instance as a screw 12, carried by a threaded socket of the shade, the inner end of which screw projects interiorly of the shade into engagement with the bulb, and for this purpose such inner end may be provided with rubber or any other suitable material. On the adjustment of this device the position of the shade relatively to the globe is regulated.

In practice the shade may be enameled or otherwise decorated to give it any desired finment of the lamp is not permitted when a circular shade is used, as in such case if the light were swung up the under half of the shade would cover the light, or such shade can be rotated relatively to the neck of the lamp by merely turning the same, thereby to reflect the light in any desired circular direction, from which it will be observed that greater advantages are obtained by the use is permitted, whereby it does not become heated, as would be the case with a solid band encircling and closely engaging the lamp at all points.

I claim as my invention- 1. The combination, with a shade adapted to partially encircle an incandescent lamp and having an integral neck portion also adapted to partially encircle one part of said lamp, of means for removably securing said shade in position and having one part thereof rigidly secured to one part of said neck portion and another part thereof detachably secured to another part of said neck portion, said means and integral neck portion cooperating to com pletely encircle said lamp; and means for maintaininga part of said shade out of contact with the lamp.

2. The combination, with a shade adapted to partially encircle an incandescent lamp and having an integral neck portion also adapted to partially encircle one part of said lamp, of a spring for removably securing said shade in position and having one part thereof rigidly secured to one part of said neck portion for swinging movement and another part thereof detach-ably secured to another part of said neck portion, said means and integral neck portion cooperating to completely encircle said lamp; and means for maintaining a part of said shade out of contact with the lamp.

8. The combination, with a shade having an integral neck portion adapted to partially encircle one part of a lamp, of a coiled spring having one part thereof rigidly secured to one edge of said neck portion and having a pair of its coils receiving and overlapping another edge of said neck portion for detachably securing said shade in position.

4. The combination,with alamp-shade having an integral neck portion adapted to partially encircle one part of a lamp, of a coiled springrigidly secured to one part of said shade and having its coils adapted for removable attachment to another part of said shade and provided with a finger-piece formed adjacent to the detachable end of said coils.

5. The combination, with a rotatable lampshade having an integral neck portion adapted to partially encircle one part of a lamp and provided with a flaring ear, of means automatically adjustable in a circular path for removably maintaining said shade in rotatable engagement with the lamp and comprising a coiled spring rigidly secured at one end to one edge of said neck portion for swinging movement and having its coils adjacent to its other end adapted for removable attachment to said flaring ear.

6. The combination of a substantially semi circular lamp-shade having a neck portion; a coiled spring rigidly secured to one part of said shade and removably secured to another part thereof for maintaining said shade in position on a lamp; and means free of connection with said neck portion for adjusting the shade toward and from the lamp.

7 The combination of a semicircular lamp shade having a neck portion adapted to engage the glass neck of an incandescent bulb; means for securing said shade in position directly on said bulb; and independent means adapted to contact with bulb for adjusting one part of said shade toward or from that portion of the lamp having the greatest diam eter.

8. The combination of a lamp-shade com prising a substantially semicircular,conicallyshaped shield having its apex adjacent to that portion of the lamp having the largest diameter, and having a neck adapted to partially encircle the lamp, said neck having a pair of flaring ears; a coiled spring rigidly secured to one of said ears and detachably secured to the other of said ears and adapted to partially encircle the lamp; and an adjusting device carried by said shield and adapted to engage the lamp adjacent to that portion thereof hav-- ing the largest diameter, thereby to move the same toward or from the lamp-bulb.

9. The combination of a lamp-shade com prising a conically shaped, semicircular shield; means for securing the same in posi tion on a lamp,whereby said shade has a rotary adjustment relatively thereto; and means carried at the apex of said member, for later ally adjusting the same relatively to the lamp;
